The winners of Britain's biggest-ever lottery prize of £56m were today revealed as 41-year-old Justine Laycock and 43-year-old Nigel Page.

The couple, who live near Cirencester in Gloucestershire, were named at a press conference in Bath, Somerset, at which they received their prize.

Page described himself as "a white van man" and said he hoped to get a "bigger white van" before adding that he wanted to get a Range Rover Sport or a BMW X5 "just to start with to get the dog and kids in". He works in property maintenance but has cancelled his jobs for the next few weeks.

Page said he bought two Lucky Dips for the EuroMillions jackpot after winning £55 in Wednesday's lotto draw. He was sitting having breakfast with one of his daughters on Saturday morning when he heard the news that a British winner had shared Friday's overall EuroMillions jackpot of £113m with one other ticket, purchased in Spain.

He finished his breakfast before logging into his lottery account online, where he received his "Congratulations" message. "I read it three or four times," he said. "I mostly leave Justine in bed on Saturday morning … I said to her you've got to come and check this."

Laycock, who has handed in her notice at the estate agents where she works, said: "He'd lost his voice, he was pointing [at the computer screen]." She said she checked the numbers. "I went in and went, 'Oh my God'. So we sat there for about a minute in silence."

Looking at her partner, she went on: "We just went into the front room, didn't we, and started to laugh. It was an amazing feeling."

The couple have three children from previous relationships – Page's daughter Ella, 12, and Laycock's son Jacob, 11, and daughter Georgia, 15. Page said Georgia's reaction was an underwhelmed "whatever".

Laycock said they had not given much thought to what they would do with the money but wanted to help their family. "Our priority is to help people who have never had this opportunity," she said. "It's an amazing amount of money."

Laycock, who had also bought her own ticket, said the couple wanted to give money to local schools in Cirencester. The couple said they would stay in the area but would move house.

"I'd like a house where I could open the back door to chuck the ball to the dog and just run and run and run," said Laycock. Page is a skydiving fan and hopes to set up his own indoor skydiving centre in the south-west.

The prize puts them among the richest people in the country, according to the Sunday Times Rich List 2009. Page would rank as the 980th richest person in Britain on the list. Based on figures released when the list was published in April, they will become wealthier than the singers Van Morrison (£50m) and Kylie Minogue (£35m).

The jackpot surpassed the £91m shared last November between two UK tickets, one bought by Les Scadding and his wife, Sam, from south Wales, and the other by the Lucky Seven syndicate, from Liverpool.
